"Ellr'hermore, )the device -l is designed to dis- Y tribute'ygthis' .fuelautomatically,uniformly y foverfgt'h N VhOl circumferential., area of 1, the generatorrl. the form: o'ffdevice h'ereinde .s cribechjith'e fuel is charged over apart only tof l `the generator 'circumference lat each f Charging operation; @bil/shells) and hence-the i AchuteV 1,0I being vslowly and, continuously rottddilne the Charging Operation A the 'v'alve lcfis" lowered,"th e shell 9 follows the chute 10 having been lowered only toY about a height substantially symmetrical with the charging door 3, whereby the shell member 9 is lowered from the position shown in Fig. 4, in which its open upper receiving end is not in communication withthe discharge side of the fuel-feeding device 25, to the position shown in Fig. 1, inwhich the fuelv fed by the device 25 can Vfall by gravity into the open top of the shell member 9. By means of the gear 18 having external teeth 19 meshing with a driven pinion 20, the shell 9 is slowly continuously rotating during the charging operation. These means for rotating the shell 9 are interconnected with'the means for operating the standard feeding drive, so as to rotate the shell 9 only a part of a complete rotation during a complete ,charging operation, as will now be described.

The pinion 20 is secured to oneV end of a shaft 21 and to the other end of said shaft 21 is secured a' bevel gear 22 adapted to mesh Awith a bevel gear 23 secured to a shaft 24 to which the vspirally arranged standard feeding means 25 are secured. By wellknown means, the feeding means 25 are actuated to-feed the fuel by a step-by-step process during one charging operation through the medium of a rod 26 connected at one end by suitable transmission devices to the shaft 24 and eccentrically connected at the other end to a shaft 27 of reduction gearing 28 which in turn is driven by motor 29. This motor 29 by suitable switch devices is adaptedcooperatively with the'actuation of the 'hydraulic cylinders governing the movements of the rods 7 and 12, to feed fuel charges in the manner plainly indicated in Figure l to the generator 1 at each down run and ata time when the valve distributor 14 -is in its lowermost position, as is well lmown in the art.` With the standard constructionV just described I have combined the described means for rotating the shell 9, and hence the chutelO, a part of a rotation so as to cause the fuel to discharge through the lower opening`31 of the Vshell 9 and upon the valve distributor 14 over an area of about one-fifth of the total circumference of the generator 1 for each entire charge of fuel fed by the vanes 25. As plainly illustrated in Figure 2, wherein the arrow indicates the direction of rotation of the shell 9 and the shaded area 30 indicates that portion of the generator area covered by one charge, and the angle aindicates exactly one-fth of the whole circumference, it will be seen that I actually cover slightly more than one-fifth of the generator area by each charge so that upon the repeated coverings of the same area of the furnace, every fth charge `will slightly overlap, resulting in the elimination of any low or otherwise defective areas between the edges of successive charges. Y

The result of the operation of the apparatus described is automatically to facilitate even distribution of the fuel around the wall of the generator 1, as plainly shown in Figure 1, and eliminate entirely any undue dumping of fuel on any .given area and also the building up of any low spots between successive series of charges or between any charges which are dumped on toV adjacent areas.
